NexentaStor 2.1 Released: Improves Industry-Leading Hardware Independent NAS/SAN Storage Solution for Virtual Environments

MOUNTAIN VIEW, CA--(Marketwire - August 17, 2009) - Nexenta Systems, Inc., delivering on its
promise to continuously improve functionality and performance, today
announced the release of NexentaStor 2.1. NexentaStor is a unified storage
solution delivering enterprise class NAS and SAN functionality, based on
the revolutionary ZFS file system. Now with over 11,000 users and in
excess of 500 paid customers, NexentaStor offers an unmatched combination
of enterprise class features and an open technology and business model that
promises to end storage vendor lock-in forever.

A webinar will be co-hosted by Nexenta and Alyseo Systems tomorrow, August
18th, at 12pm eastern time, to review the experience of customers with
NexentaStor 2.0 and to discuss new features of NexentaStor.

The focus of the webinar will be the use of NexentaStor to virtualize
underlying storage in order to provide high performance, low cost, vendor
independent enterprise storage to virtualized environments, including
Citrix / Xen, Microsoft Hyper-V and VMware. With NexentaStor almost any
underlying storage can be managed and presented to virtual servers via NFS
or iSCSI or Fiber Channel. The management of the storage for these
environments is improved through the use of the VM Data Center optional
module from Nexenta that allows for one click storage provisioning and
virtual machine cloning.

Alyseo Systems is a Paris, France based solutions provider recently named
Citrix / Xen partner of the year for France. Their Director of Technology
will co-present the webinar with Nexenta Systems.
